THE PILOT FISH. 



That the stories concerning this fish are true is reaffirmed 

 by Mr. A. H. Burnell, who says that eleven years ago, while 

 on a voyage from India to this country, his vessel was beset 

 by many calms while crossing the "line." On one of these 

 occasions, while some of the passengers were amusing them- 

 selves looking over the stern of the vessel, two beautiful pi- 

 lot fishes (Naucrates ?) were seen, and soon after a portion 

 of an unusually large shark. Immediately a hook baited 

 with salt pork was thrown overboard. When it touched the 

 water these pilot fishes were seen to approach it, and then 

 suddenly dart under the vessel. Soon a very large shark 

 appeared and received the bait. As soon as safely secured 

 the sailors drew him on deck. When a suitable opportunity 

 was given for examining him, these two pilot fishes were 

 seen attached to the body. At what particular portion they 

 attached themselves he was unable to state. They were re- 

 moved and placed in a bucket of salt water, where they swam 

 about as if nothing had happened. Am. Natural. ^ Nov. ^ ISVG. 



NEW ^VORK ON EUROPEAN FRESH-WATER FISHES. 



Professor Von Siebold, the eminent zoologist of Munich, is 

 about publishing a great work on the fresh-water fishes of 

 Europe, in which he invites the co-operation of English nat- 

 uralists. He also desires specimens of Artemia salina^ or 

 the salt-brine shrimp, for the purpose of making comparisons 

 with the varieties of this genus found throughout the world. 

 A work upon the fresh-water fishes of the United States, cor- 

 responding to those of Europe, is a very great desideratum, 

 and it is much to be hoped that some of our naturalists may 

 undertake this labor before long. 12 A,3Iarch V, 1876, 306. 



SOME CURIOUS AUSTRALIAN FISHES. 



The interest that attaches to the Australian fish known 

 as the Ceratodus {C.forsteri) is well known to naturalists. 

 M. Castelnau, in Gervais's Journal of Zoology^ calls attention 

 to several other Australian species of equal interest. These 

 are the Neoceratodus blanchardi and the Osteoglossuni lei- 

 char dt I. 



The Ceratodus forsteri attains a length of six feet, and its
